DS2 is 2 and a half, and communicates well. I have been asking him if he wants to start big boy pants, reading the books etc but he just tells me he wants his nappy, and no amount of bigging up ds1 going to the loo helps. The thing is, I have an ideal window coming up of 3 weeks of them being at home, no school runs etc and as dd is 8 months and crawling, I feel I can only achieve this if I am able to keep us all at home - has anyone had a similar constraint, and, despite what the books say, is it worth going for it?
